Part of the trend shown in the Pew and ABC/Post polls may simply be "natural tightening" -- as Republicans and Republicans-who-call-themselves-independents come home to their party. But what needs to be kept in mind is that at this late stage the remaining independent undecided or soft leaners generally constitute the least informed, least involved and, in many cases, least intelligent segment of the electorate. Or, to be perfectly blunt about it: Many of them are completely fucking clueless, which means they tend to be the most easily manipulated by the kind of limbic, cesspool politics the Rovian machine now specializes in.
